Open Graph Image Size: The Ultimate OG Image Guide (2026)
The correct Open Graph image size for every platform. Learn the ideal og:image dimensions, file format, and file size for Facebook, LinkedIn, Slack, and more.
The ideal Open Graph image size
The recommended Open Graph image size is 1200x630 pixels with a 1.91:1 aspect ratio. This is the sweet spot that displays correctly across Facebook, LinkedIn, Slack, Discord, Twitter, and most other platforms that read OG tags.
Images smaller than 600x314 pixels may not render at all on some platforms. Images larger than 1200x630 will work but waste bandwidth — the platforms downscale them anyway.
- Recommended: 1200x630 pixels (1.91:1 ratio)
- Minimum: 600x314 pixels (below this, some platforms skip the image)
- Maximum file size: 8MB (keep under 1MB for fast loading)
- Supported formats: JPG, PNG, WebP, GIF
- For square previews: 1200x1200 pixels (1:1 ratio)
Platform-specific considerations
While 1200x630 is the universal standard, each platform renders OG images slightly differently. Facebook and LinkedIn display the full 1.91:1 image. Twitter prefers 1200x628 for summary_large_image cards. Slack and Discord crop the image into a preview card.
The key is to keep important content centered. Avoid putting text or logos near the edges — platforms crop differently and may cut off edge content. A safe area of 100px padding on all sides ensures nothing important gets clipped.
Common OG image mistakes
The most common mistake is using a relative URL for og:image. Every social platform's crawler needs an absolute URL (https://example.com/image.jpg, not /image.jpg). Without it, the image will not load and the link preview will be text-only.
Another frequent issue is image caching. When you update an og:image, platforms may show the old cached version for days or weeks. To force a refresh, use a cache-busting query parameter in the URL (e.g., image.jpg?v=2) or use the platform's debugging tools.
- Relative URL: must be absolute (https://...)
- Image too small: use at least 600x314 pixels
- No alt text: add og:image:alt for accessibility
- Cached old image: append ?v=2 to force refresh
- Missing HTTPS: use https:// URLs, not http://
Testing your OG image
Use our meta tag checker to verify your og:image tag. The tool shows whether the image URL is accessible, whether it is an absolute URL, and renders a live social preview so you can see exactly how it will look when shared.
For platform-specific debugging, use Facebook's Sharing Debugger and Twitter's Card Validator. These tools force a re-crawl of your page and show you exactly what each platform sees.
Frequently Asked Questions
1200x630 pixels with a 1.91:1 aspect ratio. This size renders correctly on Facebook, LinkedIn, Slack, Twitter, and most other platforms. Keep the file under 1MB for fast loading.
The most common causes are: using a relative URL instead of an absolute one, the image being too small (under 600x314px), or the platform showing a cached old version. Use our meta tag checker to diagnose the issue.
Append a cache-busting query parameter to the image URL (e.g., image.jpg?v=2). Then use Facebook's Sharing Debugger or Twitter's Card Validator to force the platform to re-crawl your page.
